诱导引力引起的类Starobinsky暴胀

Starobinsky-like inflation from induced gravity

Gian F. Giudice, Hyun Min Lee

摘要:

我们推导出一个通用的标准,定义所有的单场模型导致Starobinsky一样的通货膨胀和普遍的预测的光谱指数和张量标量比,这是在协议与普朗克数据。在所有满足这一标准的理论中,我们挑出一类特殊的模型,它们具有在普朗克尺度下保持微扰么正性的有趣特性。这些模型是基于感应引力,普朗克质量由暴胀子的真空期望值决定。

英文摘要:

We derive a general criterion that defines all single-field models leading to Starobinsky-like inflation and to universal predictions for the spectral index and tensor-to-scalar ratio, which are in agreement with Planck data. Out of all the theories that satisfy this criterion, we single out a special class of models with the interesting property of retaining perturbative unitarity up to the Planck scale. These models are based on induced gravity, with the Planck mass determined by the vacuum expectation value of the inflaton.
